I was riding the bobsled on thursday, cruised all the way through and as I was coming out onto the road my rear wheel sounds like it exploded. Look down to see that I've blown a couple of spokes and have to walk the rest of the way to the car. Are there any recommendations where I should go to get my wheel restrung or at least trued. I could probably figure it out but between work and now that U has started again, I'd rather just ride and have a shop mechanic take care of it.
